Roadrunner To Pike’s Peak
What happens when a family heirloom gets a NASCAR heart and a date with a mountain? We brought Richard Tomlin of Apex Auto Works on to share the full story of transforming a 1968 Plymouth Roadrunner into a Pike’s Peak contender by setting the classic body over a stretched NASCAR truck chassis and dropping in a Mopar R5 P7 that sings to 9,500 RPM. The road to SEMA almost ended on the shoulder after a tow rig failure, but with help from racers and friends the car made a prime debut and drew a crowd that wanted every detail—how it was built, why it matters, and where it’s headed next.
We dig into the engineering: cutting and adding four inches to match the B-body wheelbase, aligning the shell, using NASCAR-style ride height adjusters, and balancing street presence with a proper cage, race seats, and belts. Then we climb into the thin-air problem. Pike’s Peak starts near 8,000 feet and finishes above 14,000, so we talk mid-altitude tuning targets, power loss on NA engines, and a throwback solution—variable jetting on a carb, with insight from Brad Pink, son of legendary engine builder Ed Pink. The motor has already proved itself on the mountain in a C10, and we break down the expectations for power at altitude versus near sea level.
Richard also opens the shop doors: a turbo LS7 Volvo, a refreshed ’69 Roadrunner, a twin-turbo LS G-body in paint, and a batch of Miatas, including a Lemons car that a 17-year-old is repairing while learning to wrench. We talk craft, patience, and why “toys” deserve thoughtful timelines. Along the way, we swap stories about Charlotte’s NASCAR spectacle—how great facilities make new fans—and preview a spring motorsports festival in Victoria’s Riverside Park: a tight, time-attack course through the trees designed for stunning visuals and driver challenge.
If you love bold builds, real-world engineering, and the culture that keeps car life vibrant, this one’s for you. Subscribe, share it with a friend who loves hill climbs or sleepers, and leave a review to tell us what you’d climb the mountain with.
